CardSight AI joins Northeastern’s Roux Institute founder residency

CardSight AI, a Portland-area trading card infrastructure startup, has been selected for Northeastern University’s Roux Institute Founder Residency as one of 10 companies in the program’s seventh cohort. The three-month residency gives the company access to mentors, researchers, legal and business support, and a broader network as it expands its API-based platform.

Why it matters: - CardSight AI is building core infrastructure for trading card apps, marketplaces and grading services, which could lower the time and cost for new products in a fast-growing niche. - The Roux Institute residency gives the company no-fee, no-equity support and access to Northeastern resources, which can help a Maine startup scale without leaving the state.

What happened: - CardSight AI, Inc. was selected for the Founder Residency at the Roux Institute at Northeastern University. - The startup is one of 10 companies in the program’s seventh cohort. - The cohort includes startups from across the U.S. and around the world. - CardSight AI’s residency runs from September through December 2026. - The company will then receive free membership in the Roux Incubator through August 2027.

The details: - The Founder Residency is the Roux Institute’s longest-running entrepreneurship program and has completed six cohorts. - The program charges no fee and takes no equity. - Each participating company must have at least one founder living and working in Portland for at least three months. - CardSight AI was founded in Kennebunk, about 20 miles south of Portland, and has built the company in southern Maine from the start. - Early research and development funding came from the Maine Technology Institute. - Maine ranks 13th nationally as a place to start a business, according to WalletHub. - Portland is on the Atlantic coast about 90 minutes north of Boston and has an international airport with more than 15 direct destinations. - Through the residency, CardSight AI will work with Northeastern University researchers and graduate students on the university’s downtown Portland campus. - The company will also get matched mentors, legal counsel, design and business support, and access to Northeastern’s global network of investors and corporate partners. - CardSight AI’s platform provides card identification, a structured catalog and market data through one REST API and MCP endpoints for AI agents. - The company offers SDKs for Node.js, Python, Swift, Java and .NET. - CardSight AI also provides a free tier that requires no credit card.

Between the lines: - CardSight AI is positioning itself as infrastructure, not a consumer app, which means its value depends on becoming the backend layer other builders rely on. - AI has made it easier to launch a trading card app, but CardSight AI argues the hard part remains the data foundation: accurate identification, complete cataloging and reliable market data. - The company says those foundations still require time and capital, which is why packaging them into one API could be attractive to developers and marketplaces. - CardSight AI says Maine has been a strong place to build a technology company and that programs like the Founder Residency help make a global business possible from the Portland area.

What the product does: - CardSight AI says its identification system accepts ordinary photos taken at an angle, with several cards in frame, rather than requiring one card lined up in a box on screen. - The company says image results return in under 300 milliseconds per image at 99.5% accuracy. - Coverage includes major U.S. sports, Pokémon, Magic: The Gathering and One Piece. - Printed language detection spans eight languages. - CardSight AI says new sets are supported in days rather than months. - The company says it added support for Pokémon Pitch Black and 2026 Topps Flagship Football days after release. - The CardSight AI Catalog includes more than 13 million cards organized by segment, manufacturer, release, set, card and parallel. - CardSight AI says no public canonical trading card database exists, and it treats its catalog as a standalone product. - The company’s market data layer shows transparent bid and ask information tied to specific sales. - CardSight AI does not publish a single comp or price and instead gives customers the underlying market data.

What’s next: - CardSight AI plans to use the residency to expand category coverage, deepen its market data and grow its engineering team in Maine. - The company enters the program with a growing base of paying subscribers, ranging from independent developers to enterprise marketplaces. - CardSight AI is also a member of the NVIDIA Inception program. - More information is available at the company’s website.
